Model Library & Upload

The model library page is the platform entry point: upload, list, status tracking, retry, download and delete.

Upload

Drag in or select an .ifc file (≤200MB); non-.ifc extensions and oversized files are blocked by the frontend and validated again by the backend.
After upload the model enters converting; the server queues the converter to generate XKT and metadata, and the page polls every 2 seconds until all models leave converting.
Status values: converting (being converted), ready (usable), failed (conversion failed, retryable).

List operations

Retry: re-queue conversion for a failed model.
Download: download the original IFC file (the unmodified upload).
Delete: cascades to the IFC, XKT, metadata and state files, plus the model's issues / changes / overrides.

The endpoint contracts for upload, list, retry, download and delete are in Viewer REST API.
